A spitzer bullet (from German: Spitzgeschoss, "point bullet") is a munitions term, primarily regarding fully-powered and intermediate small-arms ammunition, describing bullets featuring an aerodynamically pointed nose shape, called a spire point, sometimes combined with a tapered base, called a boat tail (then a spitzer boat-tail bullet), in order to reduce drag and obtain a lower drag ...
[26] [9] The s.S. ball projectile with a 5.9 millimetres (0.23 in) long 6° 25′ 51″ boat tail was designed for long range use and offered the best aerodynamic efficiency and external ballistic performance of any standard rifle bullet used during World War II, with a G1 ballistic coefficient between 0.593 and 0.557 (ballistic coefficients ...
The new spitzer bullet style was partially responsible for the cartridge's improved performance as it significantly reduced air drag within normal combat ranges and withstood higher accelerations in the barrel. Reverse engineering the trajectory from the previous sentence indicates a ballistic coefficient (G1 BC) of approximately 0.33.
Following the lead of French and German army commands in developing the spitzer - a pointed-tip - bullet shape, later military ball ammunition was loaded with a 10.00 g (154.3 gr) spitzer bullet fired at a muzzle velocity of 830 m/s (2,723 ft/s) with 3,445 J (2,541 ft⋅lbf) muzzle energy from a 589 mm (23.2 in) long barrel became available. It ...
The .276 Enfield was designed with the intent of being more powerful than the .303 British cartridge used in the Lee–Enfield rifles and to be at least similar in size and performance to other large, powerful early 20th century military rifle cartridges, like the .280 Ross, 7.92×57mm Mauser, .30-06 Springfield and 7.5×55mm Swiss GP11.
The 7mm Remington Magnum offers ballistics better than the .30-06 Springfield with all available bullet weights, one of the more popular loads being a 160-grain spitzer loaded to 3,000 ft/s (910 m/s).
The bullet energy is stated to be up to 1.5 times that of .25 ACP in a similar sized cartridge. It is stated to be capable of penetrating 45 layers of Kevlar soft body armor at close distances. [4] 5.45×18mm PSO (ПСО): spitzer-pointed full metal jacket bullet with lead core. [5]
The projectile was replaced in 1908 by the 9.61-gram (148.3 gr) Лёгкая Пуля (Lyogkaya pulya, "light bullet") spitzer bullet, whose basic design has remained to the present. The Lyogkaya pulya, or L-bullet, had a ballistic coefficient (G1 BC) of approximately 0.338 and (G7 BC) of approximately 0.185. [citation needed]
